P.S.

Post-scriptum:

By the way, this site hosted by Noos (the up date of these pages are not possible since I’m not anymore a subscriber, but this address is still available) was for a test to put in line an article on the Yemeni gestures (non-verbale communication) that was then published by the scientific journal Chroniques yéménites (from the CEFAS in Sanaa), in a paper version, and in an experimental web version, including about 64 small videos taken with a web cam, illustrating the gestures and their movements. See in the Publised work section this article.
